    Default Gearbox crunch- adjustable?

    My gearbox crunches very slightly going into second and third, i have read that this may be improved by adjusting the gearbox cables. Has any one tried this or know how it's done?

    Today I found out that there is a design fault with the F40 gearbox. gear crunchin in 1st and 2nd when cold and 3rd and 4th when hot , vx says to reduce your gearbox oil down from 3.2 ltrs to 2.4 ltrs to resolve the problem. No point fitting new box as design has never change so all new cars after 2007 with F40 has 2.4 ltrs as standard from factory.

    I had the same problem.

    After the DMF was replaced the mechanic filled the gearbox with 3 litres of fluid.It was a real ***** to get first gear on occasion.I took it back and he syphoned a bit out which made it much better,not brilliant mind,just much better.

    Hi, sorry i neglected to say the model, it's a 54 plate 150cdti sxi with 83k on the clock. No matter how careful i am it won't change smoothly going into 2nd or 3rd, i've tried changing very slowly and deliberately with no luck. The gearbox oil tip i'll look into as it sounds plausible.
    cheers,

    Jim.
